Frequently Asked Questions

  • How long will the shipping take? 

We have an up-to-date estimated shipping guide near the cart button.

  • I'm a skinny guy and not as muscular as the models, will these Jeans still fit me?

These Jeans give a fitted look, even on slim-legged guys, ensuring the hip, bottom and ankle area do not get excessively large and baggy.

  • I have thick thighs and jeans never seem to fit me, will these actually fit?
  • These are tailored with extra sizing in the legs to allow for thick thighs. Bodybuilders or guys with especially thick thighs, select your actual waist size and enjoy the extra room.
  • I’m not really athletic and a bit more dad-bod than bodybuilder, will these fit?

Yes, these have a flexible waist and will also allow for ”Seasonal" weight fluctuations.

  • Who don't these Jeans suit? 

Although they have a feel more relaxed than it looks, if you don’t want a skinny fit look, then we suggest our Active Tapered Slim Fit Jeans. 

  • I have had bad experiences with online shopping and I have never heard of Kojo Fit?

We have sold thousands of athletic fit clothing products to guys across the world. We only accept verified reviews from purchases. We truly care about giving the perfect fit, if you are not satisfied, we encourage size exchanges and returns. With 100% Fit, Comfort & Quality Guarantee, never get stuck with a bad fit!
